How to perform the update
We're being more cautious in pushing releases to the world.
Before we implement Google's model, we kind of treat people on the forum on the rapid track. Thus:

For people on 2.2.3 (beta), 2.2.5 will show up as auto-upgrade (for Windows/Mac)
For debian, it will be available in unifi-beta repo.
For people on 2.2.0, you can either wait or use method 2 or 3 below.

1. Auto upgrade: UniFi checks for updates daily. If you've seen an event about an update being available, go to Admin tab, find a Upgrade button. If not, refresh the page.
2. Manual upgrade: Backup your DB (Admin->Backup), uninstall the old version, install the new one, use the "restore from previous backup" in the Setup Wizard
* It's encouraged to do a backup before you upgrade.
3. Advanced upgrade for Mac/Windows: Stop the UniFi controller. Copy/move the <unifi_base>/data/ directory somewhere else. Uninstall/Re-install UniFi without starting it. Copy/move the directory back and overwrite the one just installed. Start the controller.

Downgrade
Assuming you have your configuration backup from, say, 2.2.0, you can remove 2.2.5, install 2.2.0, restore it. Then upgrade all the firmwares on the AP.
If you didn't backup and used auto-upgrade, there is a auto-backup done for you at <unifi_base>/data/backup/2.2.0.unf
